In the given figure, if ∠OAB = 40o then ∠ACB is equal to:

Detailed Solution for Test: Angle Subtended By The Chord - Question 2

In triangle OAB

OA = OB (radius of a circle)

∠OAB = ∠OBA

∠OBA = 40º (angles opposite to equal sides are equal)

Using the angle sum property

∠AOB + ∠OBA + ∠BAO = 180º

Substituting the values

∠AOB + 40º + 40º = 180º

By further calculation

∠AOB + 80º = 180º

∠AOB = 180º - 80º

∠AOB = 100º

As the angle subtended by an arc at the centre is twice the angle subtended by it at the remaining part of the circle

∠AOB = 2 ∠ACB

Substituting the values

100º = 2 ∠ACB

Dividing both sides by 2

∠ACB = 50º

Therefore, ∠ACB is equal to 50º.

Detailed Solution for Test: Angle Subtended By The Chord - Question 14
Sol^ :- Join RP and PQ. then, RP=PQ [ Since *arc RP=arcPQ* ] Now since segment RP=PQ Then, ∠POR =∠POQ = 30* [ Angles of same or equal segment ] Now, ∠ROS = ∠POQ+∠POR+∠QOS ∠ROS = 30*+30*+70* ∠ROS = 130* 《* represents DEGREE》

If ∠OAB = 40° then ∠ACB is equal to:
Detailed Solution for Test: Angle Subtended By The Chord - Question 17

In ΔQAB, OA = OB [both are the radius of a circle]
∠OAB = ∠OBA ⇒ ∠OBA = 40°
[angles opposite to equal sides are equal] Also, ∠AOB + ∠OBA + ∠BAO = 180°
[by angle sum property of a triangle]
∠AOB + 40° + 40° = 180°
⇒ ∠AOB = 180° – 80° = 100°
We know that, in a circle, the angle subtended by an arc at the centre is twice the angle subtended by it at the remaining part of the circle.
∠AOB = 2 ∠ACB ⇒ 100° =2 ∠ACB
∠ACB = 100°/2 = 50°
